Zhang Koukou · Full chronicle and history

In Hanzhong, Shaanxi, Zhang Koukou attacked the Wang family in revenge for his mother being killed 22 years earlier and the murderer receiving a light sentence, killing three members of the Wang family. After the incident he turned himself in, and was executed the following year, sparking intense public discussion about judicial fairness and private revenge.

Zhang Koukou, a veteran from Hanzhong, Shaanxi, witnessed his mother beaten to death by local thugs as a child. In 2018 he returned home and killed several members of the family responsible, a case seen as a typical instance of folk revenge against village bullies and local tyrants.
